On the left is my copy of Police Comics #74 from January 1948 and below is #82 from September 1948. Both the motorcycle covers and inside Plastic Man stories (including “The Diabolical Dr. Dimwitt”) are by creator Jack Cole. Along with Woozy Winks, the cover of #74 also shows the first and only appearance of villain Dr. Dimwitt.
